Water is critical for human development and environmental and economic sustainability. Isotopic techniques are used to help assess the quantity, quality and sustainability of this precious resource. Isotope hydrology is a nuclear technique that uncovers how water moves through the land, ocean and atmosphere. This technique provides data to facilitate informed decision making to address water management challenges. In this episode, experts dive into the science behind isotope hydrology, its application in water resource management and how it can help to achieve United Nations Sustainable Development Goals.Guests:Robert Kalin, Professor of Environmental Engineering for Sustainability at Strathclyde University, GlasgowJodie Miller, Head of Isotope Hydrology at IAEAChidambaram Sabarathinam, Acting Programme Manager and Research Scientist at the Water Research Center, Kuwait Institute for Scientific Research
